The Respiratory System

does more than move air into

and out of your lungs.

The structures of the respiratorysystem interact with structures of

the skeletal, circulatory, nervous,and muscular systems to helpyou smell, speak, and move

oxygen into your bloodstreamand waste out of it.

Lets take a look!

The skeletal systemprovides

structure to soft tissue in the

upper respiratory tract.

The perpendicular plateof the

ethmoid(the long section, shown

in blue) separates the nasal cavityinto sides.

The perpendicular plate is one

of the structures that help form

the nasal septum.

The respiratory and nervous

systems work together to identify

odors in your environment.

The respiratory system communicateswith the nervous system throughforamina in the ethmoid bone.

The olfactory bulbs(pink structures

above the olfactory nerves) receive input

from the olfactory nervesand pass it

along to the brain, which processes and

determines the odor.

The structures highlighted in blue and supported by

the laryngeal skeleton are the true vocal folds

(or vocal cords).

The vocal folds vibrate whenair is passed over them,

producing sound.

Factoid:The sinuses in theskull, the thickness of the vocalfolds, and the resonance areaof the throat give each personsvoice its own character.


5/11

The lungsare conical in shape

and have a spongy texture.

The branching structure is the

respiratory tree; bronchi branchinto smaller and smaller bronchioles,

each ending in millions of air sacs

known as alveoli, where gasexchange occurs.

Factoid:The surface area of one lungis 750 sq feet. That is the size of asingles tennis court!

Air flows from the trachea into

the bronchi, and from there into

the bronchiolesof the lungs.

The shallower angle of the right

primary bronchus is important,because when food accidentallymoves down the trachea instead

of the esophagus, its much morelikely to end up in the right lung.


7/11

The circulatory and respiratory

systems work together to

circulate blood and oxygen

throughout the body.

Air moves in and out of the

lungs through the trachea,bronchi, and bronchioles.Blood moves in and out of thelungs through the pulmonaryarteries and veinsthat

connect to the heart.

The muscular and nervous

systemsenable the involuntary

breathing mechanism.

The main muscles in inhalation andexhalation are the diaphragmand

the intercostals(shown in blue),

as well as other muscles.

Exhalation is a passive action, as

the lungs recoil and shrink when

the muscles relax.
